In one Sin Squad video, half a dozen young men can be seen wearing masks and hoodies while at one point, one of the young men can be seen pouring champagne out of a bottle on the street, while exchanging threats.

Other posts shared on Instagram show thousands of pounds being counted.

Chris Preddie, who grew up on the fringes of London gangs and drugs, told The Sun Online that social media was only making the situation more dangerous.

Chris, who now works to support young people through his charity Make Dreams a Reality, said: "It’s spinning out of control, and social media creates that hype.

"If I create a video saying I don’t like you and send it out – it’s not just the person who has seen it, it’s dozens.

"How do you feel knowing that so many people have heard that you’re an idiot? You feel like you have to retaliate. It’s a battle over who has the most kudos and respect."

Patrick Green of the Ben Kinsella Trust said more needed to be done to ensure young people understood the impact of stabbings.

He said: "Many people are worried and concerned about peer pressure as anybody else - if your friends start to carry knives, peer pressure will then see you follow.

"Gangs are using videos to promote a lifestyle, and to threaten other gang members, so social media is being used in a really negative way.

"That's something that needs to be looked at."

A YouTube spokesperson said they were working with Met Police, the Home Office and the Mayor's Office for Policing and Crime to investigate, saying: "We share the concern about the recent violence in London and obviously do not want YouTube used to provoke violence.

"(We are working) to gather intelligence so we can understand where a song lyric that might seem innocent without context is in fact a threat of violence."

The spokesperson said that law enforcement was able to directly flag videos, adding: "In the UK, we have developed policies specifically to help tackle content related to knife and gang crime and are committed to continue working constructively with experts on this issue to be part of the solution."

She said: "We will be looking to target the people we know are the most dangerous and get the intelligence to our local officers which they can use in a fast-time way.

"We will be encouraging them to not just deal with those people for violent crime, or carrying a knife, but for associated crime, or indeed any crime. If we can get people locked up, if we know they are a prolific knife criminal or a very violent person, then that is all to the good."

The police tactics are similar to those used against US gangster Al Capone, who was jailed for tax evasion.
